摘要: Preparation of cerium compounds with different structures and morphology is still a challenge in powder synthesis. CeOHCO3 CeO2 have received widespread attention because their potential applications. In this study, solvothermal method one-step precipitation was used to synthesize without use surfactant. The effects experimental conditions on the were investigated. Both X-ray diffraction SAED patterns revealed that products changed from single phase mixture CeO2. A could always be obtained by calcination air at 673 K for 1 h. Moreover, retained. Thus particles morphology, example rod-like, prism-like, polygon-like, sphere-like, cube-like, synthesized. Possible mechanisms evolution are discussed.
